Specification of Letters Patent.

Application filed December 11, 1909. Serial No. 532,605.

To all whom it may concern:

Be it known that I, CHARLES F. MURRAY, a citizen of the United States,residing at Chicago, in the county of Cookand State of Illinois, haveinvented certain new and useful Improvements in Car Sides, of which thefollowing is a specification.

My present invention contemplates the provision of simple means formaintaining closed the joints or seams between the boards or planks ofthe "all of a railway-car against the shrinkage of the wooden partsthereof. In other co-pending applications I have indicated means forsqueezing 0r tightening the boards together after the shrinkage hasoccurred, but in the present instance I prefer to employ means to bridgeany cracks o'r, openings thus occurrin In the accompanying drawings,which form a part of this specification, I have shown a preferredembodiment in which this invention may be employed for accomplishing thepurpose specified, and in these drawings,-Figure 1 is a fragmentary sideelevatlon of a car having a wall composed of a single thickness ofboards or planks, the joints between which are supplied with one form orstyle of my improved means for maintaining themclosed even though theboards contract because of shrinkage; Fig. 2 is a vertical cross-sectionon line 2-2 of Fig. 1; Fig. 3 is a fragmentary. side clev: tion, on anenlarged scale, of a portion of the car-bod wall shown in Figs. 1 and 2;Fi 4 a vertical section through the same before the shrinkage has takenplace, and Fig. 5 a similar cross-section after the contraction orshrinkage of the boards.

Referring to Figs. 1 to 5, inclusive, it will be noticed that thecar-lKuly wal is composed or built up of a sing e thickness of hoards 20disposed edge to edge. and having positioned between their edges thecentral portions 21 of metallic joiutclosing strlps of substantiallyZ-torm. and provided along their opposite edges with oppositely extendedflanges 22 and 23 adapted, respectively, to overlie the inner and outerfaces of the wall. As is clearly shown in Fig. 4, these closing stripsare of substantially the same transverse dimension as the wall itself,and the flanges 22 and 23 are bolted or riveted at 34: and 25 to theboards of the wall. The flanges 22 are therefore rigidly and fixedlysecured to the lower portions of the boards, while the flanges 23 are ina similar manner fastened to the top portions of the adjacent boards.When these boards or planks shrink or contract, as shown in Fig. 5,there is sufiicient give in the metallic fillers so that they may bedistorted as indicated without opening up the scams or joints. In otherwords, the central part 21 of these fillers, when they are first appliedto the car-wall, is at 'right angles to the flanges 22 and 23, but whenthe shrinkage has occurred this part is disposed at somewhat of anoblique angle, as is clearly illustrated in Fig. 5,

which figure shows that the joints are maintained closed by theinterposed metal. This invention also prevents the necessity ofcmploying matched lumber for car walls, and in addition to maintainingthe joints or scams between the boards of the wall,closed, also assistsin preventing lateral displacement of the individual boards of the wall.The joint closers may be niade from quite heavy stock if preferred, andas will be obvious, will materially strengthen and lend rigidity to thewall as a whole.

It will be obvious that the preferred embodiment of my invention which Ihave chosen for illustration, is capable of various changes in the size.proportion and material from which it may be made, without departingfrom the spirit of the invention or sacrificing any of the advantagesthereof;

.and therefore, I do not wish to be understood as limiting myself to theexact embmlimcnt disclosed.

I claim:

1. In a r ilway car-body wall, the combination of a pair of boa dsdisposed edge to edge, a metallic joint-closer disp sed between suchboards and having flanges overlapping one side of one board and theopposite side of the adjacent board, and means to secure said flanges totheir respective boards whereby shrinkage of the boards may occurwithout opening the joints betweenthem, substantially as described.

2. In a railway car-body wall, the combination of a pair of boardsdisposed edge to edge, a substantially Z-shaped metallic joint-closerdisposed between such boards and having one flange thereof overlappingone side of one board and the other flange overlapping the opposite sideof the other 15 board, and means for securing said flanges to theirrespective boards-whereby shrink- 1 age of the boards may occur Withoutopening the joints betvveen them, substantially as described.
